Presentation over in chaplaincy today about the theory of panspermia given my one of my mathematics academics (who actually did his degree in astrobiology).

Very interesting - if pretty inconclusive. (The practical upshot being that there's no evidence either way really, just possibilities.) I think he was hoping it would be more controversial with at least some saying 'no, it couldn't possibly be that life was seeded from elsewhere in the solar system, galaxy, universe'. Evidently we all watch too much Star Trek these days.
